1 Claim. 1

This invention relates to a gas burner unit for stoves.

It is an object of the present invention to provide a gas burner whichcan be supported in an ordinary kitchen stove to convert the stove intoa gas burning range and wherein the burner ring is supported on apedestal fixed to the bottom of the stove and is supported. on thepedestal by means of a transverse bar fitted into depending projectionson the ring.

Other objects of the present invention are to provide a gas burner unitfor stoves which is of simple construction, inexpensive to manufacture,easy to install in the stove, easy to control, and efiicient inoperation.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnection with the accompanying drawing, in which:

Fig. 1 is a perspective View of a stove broken away to show the burnerunit embodying the features of the present invention.

Fig. 2 is a vertical sectional View taken on line 2--2 of Fig. 1.

Referring now to the figures, I9 represents a stove in Which our burnerunit, indicated generally at II, is installed. The burner unit comprisesa pedestal I2 having a round base i3 which can be attached by screws Mto the bottom of the stove. On the upper end of the pedestal I2 there ismounted a transverse member I5 which can be pivoted and be movedlaterally to a desired position to receive a slotted dependingpropection I9 of a gas ring or manifold IT. The transverse member i5 issecured to the top of the pedestal by a bolt I8 and about which thetransverse member I5 can be adjusted.

The ring I! has a raised portion I8 through which outlets I9 extend toemit gas between concentric and perforated sleeves 2i and 22. A cover 23having a handle 24 may be rested upon the internal sleeve 2| to confinethe burner flame to an annular shape leaving the upper ends of thesleeves.

A neck 25 extends from the ring ii and has an adjustable air inletchamber 26 thereon. A pipe 21 extends through the neck 25 and thechamber 29 and into a thermal control unit 28 which can be controlled oradjusted by a button 29. A thermally responsive element 3I extends fromthe contro it to a point near to the flame. An inlet pipe 32 enters thecontrol 28.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claims.

I-Iaving thus set forth and disclosed the nature of our invention, whatis claimed is:

A gas burner unit for stoves comprising a pedestal and a horizontalmember, a gas burner manifold'ring having upwardly directed ports anddepending projections, the latter having recesses receiving the saidhorizontal member, the latter supporting thereby the gas burner manifoldring, concentric perforated sleeves supported upon the manifold andextending upwardly therefrom on opposite sides of said ports, and apivot bolt securing the horizontal member to the pedestal substantiallyin the center of said gas burner manifold ring and a neck portionextending from the latter, a gas inlet extending into said neck portion,and an adjustable air inlet member about the gas inlet and secured tothe neck portion.
